Description of the workplace

The Faculty of Science conducts research and education within Biology, Astronomy, Physics, 
Geosciences, Chemistry, Mathematics and Environmental Sciences. The Faculty is organized into 
nine departments, gathered in the northern campus area. The Faculty has approximately 1500 
students, 330 PhD students and 700 employees. The Biology Department has approximately 450 
students, 75 postgraduate students and 300 employees.

Biology is the broad subject about all living things. It encompasses everything from processes at 
the molecular and cellular level to global processes at ecosystem level. The subject is divided into 
a range of sub-disciplines and specialisations. The PhD programme at the Department of Biology 
includes many of these specialisations, from molecular biology to applied ecology, from viruses 
and individual cells to evolutionary biology and global biodiversity. Taking on research studies at 
the Department of Biology generally means focusing on a delimited part of the research area of 
biology and may include field studies, experiments, theoretical studies, or a combination of 
The advertised project requires an interdisciplinary approach, and the team of researchers to 
support the project has been assembled to include expertise in biogeochemistry, fungal 
taxonomy, metabolic strategy and the expertise to probe transformation and mobilization of Fe 
and OC. Main supervisor will be Prof. Emma Kritzberg with a background in aquatic 
biogeochemistry with a particular focus on links and transformations between and across 
compartments of the landscape ( 
Kritzberg’s group has made important contributions to current knowledge about freshwater 
browning, and been pioneering when it comes to the role of iron to this process and linking 
browning to land-use change. Her group has through interdisciplinary collaborations contributed 
to much of the novel knowledge about transport and transformations of Fe that provides the 
starting point for the proposed project.

Other key persons to the project are Prof. Håkan Wallander (Dept of Biology), Dr. Dimitrios Floudas (Dept of Biology), Prof. Per Persson (Centre for 
Environmental and Climate Research) and Dr. Susan Nehzati (Max IV).

Work duties and responsibilities

The role of fungal communities in controlling mobilization of organic carbon (OC) and iron (Fe) 
from forest soils.

This project aims to synergize forestry management with sustainability. The scientific goal is to 
understand how fungal communities influence mobilization of iron (Fe) and organic carbon (OC) 
from forest soils. In the background are striking increases in terrestrial export of Fe and OC to 
surface waters resulting in browning of aquatic systems. Coniferous afforestation has been 
shown to contribute to these trends, e.g. mobilization of Fe and OC is enhanced under mature 
spruce forests. This may link to differences in the fungal community, where brown-rot and 
white-rot fungi dominate in coniferous and deciduous forests respectively. It may also be linked 
to the practice of ditching peatsoils to promote forestry which increases activity of mycorrhizal 
fungi. We expect that differences in fungi-induced biogeochemistry have a strong impact on the 
decomposition processes and thereby the leakage of Fe and OC to surface waters. The project 
combines controlled laboratory experiments and field-based investigations. Synchrotron-based 
imaging and spectroscopy of wood/soil/soil solution will monitor structural and chemical 
modification during fungal decomposition. Complementary vibrational spectroscopic techniques 
will track decomposition and mobilization. By integrating experimental and observational efforts 
we can reveal which process/es underpin transformations and fluxes observed in the field.

You will be responsible for performing field measurements and laboratory experiments, with the 
overall objective to enhance our knowledge of how fungal communities influence Fe and OC 
mobilization from soils to water. You will apply advanced methods to characterize fungal 
communities, organic matter composition and Fe speciation. You will with increasing degree of 
responsibility analyse and interpret data, and present and discuss results in manuscripts to be 
submitted to scientific journals. You will take courses to provide you with knowledge and tools to 
manage the research project and to become an increasingly independent researcher.

At times the research will require long workdays over prolonged periods of time and travels 
within and outside of Sweden, and it is therefore essential that the candidate shows flexibility.
You will present results from the research project at international conferences.
The training implies a secondment of 3-12 months at MAX IV laboratory in Lund, Sweden
